Substituted foot is a metrical variation in which one poetic foot in a line of verse is replaced by another type of foot, altering rhythm and emphasis without departing from the poem’s established meter pattern entirely. This technique can create surprise, highlight a particular word or idea, or avoid monotony. For instance, in an iambic line, a trochee might be substituted at the beginning to add force, or a spondee inserted to slow the pace, showcasing the poet’s control over metrical nuance.

Substituted foot replaces an expected metrical foot (e.g., trochee in iambic line) for emphasis. Related to non-counted syllable. Scan carefully—substitutions often highlight key words; too many, however, undermine the base meter’s stability.
